Castellan MWG M4 Magazine Well Grip Black

If you play fast or play a lot of CQB, you’ve probably found yourself gripping your mag well. It feels natural to pull the gun in tight and close with that grip. Why not make it even better? With the MWG you get several different advantages. On top of enhanced ergonomics, you’ll get an enhanced flared mag well, and prevent any pressure being applied to your magazine. Which reduces feeding-related problems!
